Telekom Center Athens
Greece's largest indoor arena: four 35-meter pillars, an Olympic basketball final, and daylight pouring through the roof.

Completed in 1994 and renovated for the 2004 Games, this 19,000-seat arena in Marousi hosted artistic gymnastics, trampolining, and the basketball finals of the Athens Olympics. The A-frame roof was engineered so natural light floods the floor during the day — unusual for a venue this scale. Now leased to Panathinaikos B.C. for 49 years, it operates as a live sports and events venue under its 2025 rebrand.
What to look for
- Four pillars each 35 meters tall, spaced 108 meters apart, that carry the signature A-frame roof
- Natural light inside the bowl — the structure was deliberately built to draw daylight in
- The basketball floor layout, scene of the 2004 Olympic finals
Located in Marousi, northern Athens; check the Panathinaikos B.C. schedule for game-night access to the arena interior.
